Reactions of 3-chloroperbenzoic acid with 2,3-dichloro-1-butene (1a), 2,3-dichloro-3-methyl-1-butene (1b), (Z)- and (E)-1,2-dichloro-2-butene (1c, d) and with 1,2-dichloro-3-methyl-2-butene (1e) afforded the corresponding epoxides (2a - e).They rearranged slowly at room temperature and fast at elevated temperatures to form the corresponding isomeric α,α'-dichloroketones (3a, b).Reactions of the epoxides with AgBF4 produced α-chloro-α'-fluoroketones.
